BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to browser technology.

2. Background Art

Computer software frequently provides a throbber (e.g., spinning hourglass, beachball, etc.) while a resource loading is in progress. This masks the fact that the software does not know how long the task will take to complete. Modern web browsers use such a throbber while a resource (e.g., page) loading is in progress. However, because the activities of the browser are masked behind the throbber, the browser may feel slow as a result. For example, a SAFARI browser available from Apple, Inc. has a not-enabled-by-default throbber, a circular progress meter, in the location bar that circles uniformly as the connection proceeds. An ITUNES application available from Apple, Inc. also has a meter that uniformly circles as a connection proceeds. These uniform throbbers are unable to visually communicate the ‘waiting for server to respond’ state of a transfer, and do not animate during that period of time.

BRIEF SUMMARY OF THE INVENTION

Embodiments of the present invention relate to multi-stage throbbers that can be used to communicate stages of progress of resource loading in browsers to users. In an embodiment, a method for communicating resource loading progress in a browser is provided. The method includes evaluating the resource loading progress, identifying a throbber stage representative of the evaluated resource loading progress, and outputting multi-stage throbber data for rendering a multi-stage throbber at the identified throbber stage.

In another embodiment, a device that communicates stages of resource loading progress in a browser using a multi-stage throbber comprises a progress evaluator and a throbber stage identifier.

System Overview

FIG. 1 is a diagram of exemplary system 100 that uses a multi-stage throbber to visually communicate stages of resource loading progress to a user viewing a browser. System 100 includes a computing device 105, display 107, and resource provider 140. Computing device 105 may be coupled to display 107, and may be coupled via one or more networks 130 to a resource provider 140.

Computing device 105 may be any type of computing device including, but not limited to, a computer, workstation, distributed computing system, embedded system, stand-alone electronic device, networked device, mobile device (e.g. mobile phone or mobile computing device), rack server, television, game console, set-top box, kiosk, or other device having at least one processor and memory.

Computing device 105 includes a browser 110 and a renderer 115. Browser 110 processes resource load requests and displays the loaded results for the user. In one embodiment, for example, browser 110 may be a web browser that can be used by a user to access resources from web servers. In alternative embodiments, browser 110 may be other types of browsers for browsing remote or local content.

According to an embodiment, browser 110 may include any device, application or module that enables a user or computer to navigate and/or retrieve data from another data source, typically over a network. Browser 110 may include any conventional browser including but not limited to, for example, FIREFOX available from Mozilla Foundation Inc., INTERNET EXPLORER available from Microsoft Corp., SAFARI available from Apple, Inc., and OPERA available from Opera Software ASA. Browser 110 may also be a multi-process browser as described in “Multi-Process Browser Architecture,” by Fisher et al., U.S. Provisional Appl. No. 61/052,719, filed May 13, 2008. According to a further embodiment, browser 110 may also be configured to use any number of protocols, including Web protocols such as HTTP.

Browser 110 can send a request over network 130 to resource provider 140 and receive a response from resource provider 140 via computing device 105. As an example, not to limit the present invention, the request may be a hypertext transfer protocol (HTTP) request. The HTTP request may contain parameters entered by a user using a user interface at computing device 105. The response may be an HTTP response. An HTTP response may contain web content, such as a hypertext markup language (HTML), images, video, or multimedia content. Browser 110 may exist within or be executed by hardware in computing device 105. For example, browser 110 may be software, firmware, or hardware or any combination thereof in computing device 105.

Multi-Stage Throbber Generator

According to an embodiment, browser 110 includes a multi-stage throbber generator 120. Multi-stage throbber generator 120 generates data for output to renderer 115 to enable rendering of a multi-stage throbber. Multi-stage throbber generator 120 includes a stage analyzer 122, a progress evaluator 124, and a throbber stage identifier 126.

State analyzer 122 analyzes a resource loading process and decides the state of the resource loading. The state, for example, may be “waiting for response from resource provider”, or “transferring resource from resource provider”, etc. The examples are illustrative and are not intended to limit the present invention.

Progress evaluator 124 evaluates the progress of the resource loading. In one example, this progress evaluator may include estimating the remaining time to complete the resource loading given the analyzed state. For example, in one embodiment, progress evaluator 124 may estimate how much longer the browser has to wait for a response from resource provider 140 or the remaining transferring time to load the resource from resource provider 140.

Throbber stage identifier 126 identifies a stage of the multi-stage throbber representing the evaluated progress of the resource loading process. In one embodiment, throbber stage identifier 126 may also identify a graphical element corresponding to the identified throbber stage of the multi-stage throbber. Multi-stage throbber generator 120 then output data to renderer 115 to enable rendering of a multi-stage throbber at the identified throbber stage.

Renderer 115 receives the data output from multi-stage throbber generator 120 and renders the data to obtain display data for a multi-stage throbber that can visually communicate the stage of progress of the resource loading in the analyzed state on the browser to a user. Renderer 115 may be any type of renderer. In one example, renderer 115 can render the data output from multi-stage throbber generator 120 to obtain data that can be stored in a frame buffer (not shown) for display on display 107.

Browser 110, multi-stage throbber generator 120, state analyzer 122, progress evaluator 124, throbber stage identifier 126, and renderer 115 may each be implemented as software, hardware, firmware, or any combination thereof.

Network 130 can be any network or combination of networks that can carry data communication. In addition, network 130 also contains sites that can be accessed for information retrieval. Such networks can include, but are not limited to, local area networks, medium area networks, and/or wide area networks such as the Internet. They can support protocols and technology including, but not limited to, World Wide Web protocols and/or services. Intermediate web servers, gateways, or other servers may be provided between components of system 100 depending upon a particular application or environment.

Resource provider 140 provides resources to be loaded in browser 110. In one embodiment, resource provider 140 may include a web server. A web server is a software component that responds to an HTTP request with an HTTP response. As illustrative examples, the web server may be, without limitation, an Apache HTTP Server, Apache Tomcat, MICROSOFT Internet Information Server, JBOSS Application Server, WEBLOGIC Application Server, or SUN JAVA System Web Server. The web server may contain web applications which generate content in response to an HTTP request. The web server may package the generated content and serve the content to a client in the form of an HTTP response. Such content may include HTML, extensible markup language (XML), documents, videos, images, multimedia features, or any combination thereof. This example is strictly illustrative and does not limit the present invention.

Method for Visually Communicating Resource Loading Progress Stages

FIG. 2 illustrates a flowchart of an exemplary procedure 200 for visually communicating stages of progress during resource loading to a user using a multi-stage throbber according to one embodiment (steps 205-270). Although procedure 200 will be described for brevity with reference to system 100 shown in FIG. 1, procedure 200 can be used in other systems for visually communicating resource loading progress on browsers with users.

In step 205, one or more properties of a multi-stage throbber are selected. The properties of the multi-stage throbber may be pre-determined or selected by a browser user. The browser may be browser 110 of system 100. In one embodiment, the properties may include a type of a multi-stage throbber graphical element. For example, types of multi-stage throbber graphical elements may include but are not limited to, an hourglass, a spinning wheel, a circular arrow, icon, image, text, or figure. These examples are strictly illustrative and are not intended to limit the present invention.

The properties of the multi-stage throbber may also include a display mode. The display mode identifies how to display or animate the multi-stage throbber. For example, in one embodiment, the display mode property may be one for rotating the multi-stage throbber. In such a display mode, a rotating angle of the multi-stage throbber corresponds to the progress of the resource loading. In another exemplary embodiment, a display mode may be a coloring of the multi-stage throbber. In this display mode, the saturation level of the color may correspond to the progress of the resource loading. Alternatively, different colors may correspond to different levels of the resource loading progress. In yet another exemplary embodiment, the display mode may be resizing the multi-stage throbber. In such display mode, the size of the multi-stage throbber corresponds to the resource loading progress. Animation can also be used. These examples are strictly illustrative and are not intended to limit the present invention.

In step 210, browser 110 receives or initiates a request to load resource from a resource provider. The resource provider may be resource provider 140. The resource, for example, may be HTML, extensible markup language (XML), documents, videos, images, multimedia features, or any combination thereof. These examples are strictly illustrative and does not limit the present invention.

In step 220, browser 110 starts to load the requested resource from resource provider 140. During the resource loading process, a multi-stage throbber generator of browser 110 checks the state and progress of the resource loading process. The multi-stage throbber generator may be multi-stage throbber generator 120.

The resource loading process may have multiple stages or states. For example, in one embodiment, the states of resource loading may include, but not limited to, “waiting for response from resource provider”, “transferring resource from resource provider”, “connecting to resource provider”, etc. Thus, in step 232, state analyzer 122 analyzes the state of the resource loading. Once information of the state of the resource loading is obtained, in step 234, progress evaluator 124 evaluates the resource loading progress given the analyzed state. In one embodiment, progress evaluator 124 estimates how much time remaining to complete the part of the process in the state. For example, in one embodiment, if the resource loading process is waiting for response from resource provider 140, progress evaluator 124 estimates the remaining time to receive the response from resource provider 140. If the resource loading process is transferring resource from resource provider 140, progress evaluator 124 estimates the remaining time to complete the transfer. These examples are strictly illustrative and are not intended to limit the present invention.

Once the state and the progress of the resource loading are evaluated, in step 236, throbber stage identifier 126 identifies a throbber stage representing the state and the progress of the resource loading.

In step 238, multi-stage throbber generator 120 outputs multi-stage throbber data for rendering the multi-stage throbber at the throbber stage (identified in step 236) and according to the one or more properties selected in step 205.

For example, in one embodiment, if the display mode is rotating the multi-stage throbber, the multi-stage throbber data output may identify a rotating direction and a rotating angle. The rotating direction corresponds to the state of the resource loading, e.g. counterclockwise for “waiting for response from resource provider” and clockwise for “transferring from resource provider”. The rotating angle is corresponding to the progress of the resource loading in the state. For example, the rotating angle may be calculated such that it is proportional to the estimated completion time of the resource loading in the state.

In another embodiment, if the display mode is coloring the multi-stage throbber, the multi-stage throbber output data may identify a color and a saturation level of the color. The color is corresponding to the state of the resource loading, for example, “red” for “waiting for response from resource provider” and “blue” for “transferring from resource provider”. The saturation level of the color is corresponding to the progress of the resource loading in the state. For example, the more saturated color indicates the closer to the completion of the resource loading in the state. Other types of coloring schemes to visualize the resource loading progress can also be used in alternative embodiments.

In yet another exemplary embodiment, if the display mode is resizing the multi-stage throbber, the multi-stage throbber data may identify a color and a size of the multi-stage throbber. The color is corresponding to the state of the resource loading, for example, “red” for “waiting for response from resource provider” and “blue” for “transferring from resource provider”. The size of the multi-stage throbber is corresponding to the progress of the resource loading in the state. For example, the multi-stage throbber may be small and red when the resource loading starts and become bigger and blue when the resource loading approaches completion.

These examples are strictly illustrative and are not intended to limit the present invention. Other types of graphical elements and display modes (or combinations thereof) may also be used for rendering the multi-stage throbber.

In step 240, renderer 115 renders the output multi-stage throbber data to obtain display data for the corresponding multi-stage throbber.

In step 250, the obtained display data for the rendered multi-stage throbber is displayed on a pre-determined or user-specified location on the browser. For example, the rendered multi-stage throbber may be displayed on the top left corner of the tab displaying the content corresponding to the loaded resource. Users can also specify a location where the multi-stage throbber is displayed.

In step 260, multi-stage throbber generator 120 checks whether the resource loading process is complete. If the resource loading is not complete, multi-stage throbber generator 120 goes back to step 230, to analyze and evaluate the resource loading state and progress again. Otherwise, multi-stage throbber generator 120 proceeds to step 270, displays the favicon (e.g. the logo of the resource) on the browser and terminates procedure 200.

Further Examples

FIGS. 3A-3C illustrate examples of using a multi-stage throbber displayed at different stages to indicate the resource loading progress according to one embodiment of the invention. FIG. 3A shows a top portion of a tabbed browser display 300 a. Tabs 310 a-c are tabs corresponding to different locations (i.e., URLs, file names or other identifiers). Multi-stage throbber 320 a is an icon indicating the resource loading progress in tab 310 c. In particular, multi-stage throbber 320 a is a circular graphical element with its arc length being a function of (such as proportional to) the estimated completion time of the resource loading progress. Icons 330 a and 330 b are favicons for the resource displayed in tabs 310 a and 310 b respectively. In FIG. 3B, as the resource loading process in tab 310 c continues to a different state, multi-stage throbber 320 b has a longer arc length compared to multi-stage throbber 320 a of FIG. 3A. As the resource loading process in tab 310 c continues to a still different state of being nearly completed, multi-stage throbber 320 c in FIG. 3C appears as almost a full circle.

In one exemplary embodiment, the multi-stage throbber is displayed on the tab of the browser. Such feature may allow the browser to communicate the resource loading progress with a user even when the resource is loading in a background tab. Thus, the user does not need to bring the tab to foreground to check the progress. This is extremely useful when there are multiple resource loading processes at different tabs on the browser at the same time.

By using a multi-stage throbber, the browser can visually communicate with the user about stages of a resource loading progress for better user experience.
